They are street legal because they are DOT approved. But is it smart to run these on the streets? NO!! They are not made for the streets, you will wear out more heat cycles and reduce the life the tire. The tires are really sticky, and will pick up lots of rock and debree fromt he streets tossing it at your fender well and chipping off paint. And if you do get stopped, unless your tires are brand new with 4/32nds tread depth, you might get a ticket for having bald tires. Tires are legally bald below 3/32nds of tread depth left.
